devtools 라이브러리 추가 후 Recompile을 통해서 화면이 변경되었는데, 이 프로젝트가 아닌 다른 프로젝트에서도 첫화면이 이프로젝트의 첫화면으로 실해되는데 어떻게 해야하는 건가요??

안녕하세요, 나도코딩 선생님...ㅎ 동영상 강의들 중 섹션 14. 입출력과 파일을 보다가 궁금증이 생겨서 질문을 하게 되었습니다...ㅎ(1) 섹션 14. 입출력과 파일을 공부하면서, 파일을 읽는 여러 가지 방법들을 접하고 있습니다. 공부하면서 BufferedReader, FileReader, Scanner등 여러 가지 방법들이 있는데, 이들은 어느 때 쓰이는 것이 가장 좋은가요? 예를 들면, BufferedReader는 큰 용량의 파일을 읽는데 적합하다 던가, 아니면 Scanner는 키보드 입력을 받는 것 외에도 파일을 읽고자 할 때, FileReader와 같은 역할을 한다 이런거요!만약 어느 한 텍스트 파일을 읽고자 할 때, Scanner를 예로 들면, 이렇게 코드를 적어볼 수 있을까요? 모든 건 이미 import가 있다고 가정하고 작성해봤습니다...ㅎ:... // 이전 코드 생략 try { File file = new File("testing.txt"); Scanner scanner = new Scanner(file); while(scanner.hasNext()) { System.out.println(scanner.next()); // 여기서 만약에 여러 줄들로 이루어진 텍스트에서 한 글자씩 따오려면, // 이전에 문자열 관련 질문 처럼 scanner.next().charAt을 쓰나요? } scanner.close(); } catch (FileNotFoundException e1) { e1.printStackTrace(); // 예외 처리 1 } catch (IOException e2) { e2.printStackTrace(); // 예외 처리 2 }(2) 섹션 14에 있는 퀴즈 #13과 관련된 질문입니다! 제가 try문 안의 String input; scanner의 호출 스택(순서)을/를 제대로 이해했는지 알고 싶습니다...ㅎ... // 이전 코드 생략 Scanner scanner = new Scanner(System.in); try (BufferedReader br = new BufferedReader(new FileReader("saying.txt"))) { ... // 퀴즈 시작 및 제목 출력 String quiz; String answer; String input; while (true) { quiz = br.readLine(); answer = br.readLine(); if (quiz == null || answer == null) { break; } System.out.println(" (문제) " + quiz); System.out.println(" (답 입력) "); input = scanner.next(); ... // input.equal(answer), if-else문 생략 } ... } catch (IOException e) { e.printStackTrace(); // 예외 처리 }여기 이 코드에서, quiz랑 answer는 1줄 1줄 br.readLine();을 통해 단어 및 문장들을 인식하는 반면, 입력하는 답안의 경우에는 우선 try문 안에서 String input;을 선언하고, 대입 연산자 = 를 통해 .next();로 입력을 받은 다음, string으로 선언된 input을 .equal();로 입력받은 값과 정답을 비교하여 최종 결과를 출력하는 건가요?프로그래밍 언어를 공부하다보니 여러 질문들과 궁금증이 많이 쌓이는데, (특히 최근에 들어선 더 많아졌네요...ㅎ) 그 때마다 제 궁금증을 답글을 통해 잘 해소줘서 진심으로 감사합니다..ㅎ :)

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예)[질문 내용]의존성에서 thymeleaf를 추가하지 않는다면, templates 이란 폴더가 기본적으로 포함이 안되어있는 상태인가요?만약 thymeleaf를 사용하지않고 리액트와같이 view 부분을 따로 빼서 프로젝트를 진행할때는 controller에서 어떻게 return 값을 보내줄수있나요? 추가질문으로 model이 무슨역할을 하는건지 궁금합니다

안녕하세요.test를 일부러 다른 member 이름으로 했는데도 계속 초록색 체크(성공 표시)가 뜹니다..!gradle 속성도 바꿔보았는데요 노란색 박스에 보시면 실행 자바는 19버전이더라구요..어떻게 해결할 수 있을지 여쭙고 싶습니다!감사합니다.

안녕하세요 강사님CASCADE 강의를 들으면서 공부 도중 여러가지 테스트를 해보면서 이해가 안되는 부분이 있어서요제가 이해한 내용으로는 CASCADE를 사용하면 Parent 필드에 있는 children 도 연관관계의 주인의 기능을 할 수 있다고 이해했는데요위 코드를 실행한 결과 findChild1은 삭제 되지 않고 db에 남아있었습니다.또한 em.remove(findChild1)을 지우고 list.remove(0)을 넣어도 데이터가 그대로 남아 있었습니다.CASCADE 속성은 ALL으로 사용했습니다.질문 1영속성컨텍스트에 child 객체 두개와 children 내부에 child 객체 두개가 있어서 그런건가요?질문2그리고 고아객체 강의를 보고 이해가 안되는게CascadeType.ALL + orphanRemoval=true 을 쓰는 것과CascadeType.ALL 만 쓰는 것에 차이가 있을까요?  

 몰론 페이지 맨 위에 강의출처 링크는 남겨놓겠습니다!! 동영상을 다시 보는 것 보다 제가 따로 코드를 따라치며 생각을 정리하는 게 효율적일 것 같아서요... 괜찮을까요??c++을 부랴부랴 배우고, JAVA를 뒤늦게 배우는데 양질의 강의를 제공해주셔서 감사합니다! :)

JpaRepository를 상속 받는 인터페이스 정의@NoRepositoryBean기본 구현체를 상속 받는 커스텀 구현체 만들기@EnableJpaRepositories에 설정repositoryBaseClass기본 리포지토리를 커스터마이징할 때 위와 같은 방법으로 하라고 알려주셨는데요, 인터페이스에서 JpaRepository를 상속받았는데 구현체에서 SimpleJpaRepository<T, ID>를 상속받는 이유를 모르겠습니다. 구현체가 (JpaRepository를 상속받은)인터페이스를 구현하니까 JpaRepository 기능을 사용할 수 있지 않나? 라고 생각했습니다.아마 제가 상속과 구현 개념이 제대로 잡혀있지 않아서 그런 것 같습니다. 설명해 주시면 저에게 많은 도움이 될 것 같습니다. 좋은 강의 만들어주셔서 감사합니다!

안녕하세요, 선생님...ㅎ 갑작스럽게 생각난 질문인데요...ㅎ 제가 예시로 아래처럼 클래스를 만들어 봤는데, 혹시 상속받은 클래스의 super(); 생성자 안에 이렇게 메소드도 넣을 수 있나요? 자바를 공부하면서 지금 여러 소스 코드들을 보고 있는데, 어느 소스코드는 super(); 생성자 안에 메소드를 집어 넣은 경우가 있더라구요?! 만약에 이렇게 만들 수 있다면, 언제 어느 때 가능할까요?클래스는 정말 제가 생각나는대로 적어서 컴파일 에러 같은 건 생각하지 않았습니다. 부디 너그럽게 봐주셨음 합니다...ㅎclass Kid extends SomethingAwesome { Kid(int age) { super(comment(age)); // super() 생성자 안에 comment메소드 삽입 } public String comment(int age) { String saySometing = ""; if (age > 3 && age < 7) { saySomething += "엄마, 과자 사줘!"; } else if (age >= 7 && age < 11) { saySomething += "엄마, 이젠 로보트 사줘!"; } return saySomething; } public static void main(String[] args) {...} // 메인 메소드 실행 }또한 일반적인 생성자 (Constructor)를 만들 때도, 생성자 안에 전달 값외에도 메소드를 넣을 수 있는가요? 이것도 마찬가지로 위에 예시로 코드를 적은 것 처럼 제 나름대로...ㅎ 써봤습니다...ㅎ 위의 예시 처럼 정말로 생성자 안에 메소드를 넣는게 가능한지 궁금해서 약간 무리수를 두면서(?) 코드를 적어봤습니다..ㅎ 이것도 너그럽게 봐주세요...ㅎ 감사합니다 : )class ThankYouNote { // 제가 생각해도 좀 많이 이상하지만, // 메소드를 이렇게 선언해서 do = thanks(); // this.do = do; 이렇게는 많이 무리수죠? ㅠㅠ // 저렇게 위 클래스 처럼 super 생성자 안에 메소드를 넣는건 처음봐요 ㅠㅠ ThankYouNote() { thanks(); // this(thanks()); // 너무 많이 무리수 인듯하지만 일단 적어봤습니다...ㅠㅜ } public void thanks() { System.out.println("나도코딩 선생님, 감사합니다. :)"); } public static void main(String[] args){ ... } // 메인 메소드 실행 }

안녕하세요. 9강 returnBookTest() 질문 드립니다.저는 강의 내용을 듣기 전에 미리 제가 테스트코드를 짜보고 이후에 비교해가면서 강의를 수강하는데요. 제가 짠 코드는 실패를 해서 문의드려봅니다.@Test @DisplayName("책 반납 성공") fun returnTest(){ //given val user = User("phd",31) userRepository.save(user) val book = Book("testBook") bookRepository.save(book) val loanHistory = UserLoanHistory(user,"testBook",false) userLoanHistoryRepository.save(loanHistory) //when assertThat(loanHistory.isReturn).isFalse() bookService.returnBook(BookReturnRequest(user.name, "testBook")) //then assertThat(loanHistory.isReturn).isTrue() }저는 loanHistory 엔티티가 영속성 컨텍스트에 있기 때문에 user.userLoanHistroy 엔티티가 바뀔 때 loanHIstroy 객체의 상태 값 도 바뀔거라고 생각했는데요. 생각해보니까 각 엔티티를 save() 하는 메소드들의 트랜잭션이 각각 달라서 영속성 컨텍스트에 loanHistroy 객체가 없었을것 같아요. 뭔가 제대로 확인 할 방법은 없어서 그렇게 유추만 하고 있는데, 제가 유추한 내용이 맞을까요?... 강의 언제나 잘 보고 있습니다. 감사합니다!

public class PhantomReferenceExample { public static void main(String[] args) throws InterruptedException { BigObject strong = new BigObject(); ReferenceQueue<BigObject> rq = new ReferenceQueue<>(); BigObjectReference<BigObject> phantom = new BigObjectReference<>(strong, rq); strong = null; System.gc(); Thread.sleep(3000L); // TODO 팬텀은 유령이니까.. // 죽었지만.. 사라지진 않고 큐에 들어갑니다. System.out.println(phantom.isEnqueued()); Reference<? extends BigObject> reference = rq.poll(); BigObjectReference bigObjectCleaner = (BigObjectReference) reference; bigObjectCleaner.cleanUp(); reference.clear(); } }위에 코드에서 커스텀하게 만든 BigObjectReference 로 형변환을 하고 cleanUp을 따로 호출 하는 부분이 이해가 잘 가지 않습니다. cleanUp 메서드도 단순히 출력만하는데굳이나 상속을 받아서 커스텀하게 만든 형태가 만든게 무의미한 것 같습니다.  기선님이 의도한 소멸되는 시점을 확인하고자 하면 아마 아래와 같이 clear 메서드를 오버라이딩하는게 좀 더 맞지 않나 조심 스럽게 의견을 내봅니다.public class BigObjectReference<BigObject> extends PhantomReference<BigObject> { public BigObjectReference(BigObject referent, ReferenceQueue<? super BigObject> q) { super(referent, q); } @Override public void clear() { super.clear(); System.out.println("clean up"); } }public class PhantomReferenceExample { public static void main(String[] args) throws InterruptedException { BigObject strong = new BigObject(); ReferenceQueue<BigObject> rq = new ReferenceQueue<>(); BigObjectReference<BigObject> phantom = new BigObjectReference<>(strong, rq); strong = null; System.gc(); Thread.sleep(3000L); // TODO 팬텀은 유령이니까.. // 죽었지만.. 사라지진 않고 큐에 들어갑니다. System.out.println(phantom.isEnqueued()); Reference<? extends BigObject> reference = rq.poll(); reference.clear(); } } 출력화면 

cmd에서 ./gradlew /gradlew gradlew gradlew build 다 쳐봤는데내부 또는 외부 명령, 실행할 수 있는 프로그램, 또는 배치 파일이 아닙니다. 라고 나오거나ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk-11\binPlease set the JAVA_HOME variable in your environment to match thelocation of your Java installation. 라고 떠요..그리고 버전 확인해봤는데 저렇게 나오는 게 맞나요?다른 분들 질문한거 웬만한거 다봤는데 여기서 더이상 어떻게 진행해야 될 지 모르겠어서 막막하네요ㅠㅠ

[질문 내용]회원 목록 조회 강의수강중입니다.어플리케이션을 재시작 할때마다 DB에 테이블이 재생성이 되면서기존 데이터가 사라집니다.yml에 ddl-auto : create설정 때문인 것 같은데,none, 이나 update로 설정하면 테이블의 재생성은 방지가 되는데,최초 구동 시 JPA가 테이블을 생성하는것도 막히는건지 궁금합니다.

안녕하세요, 다름이 아니라 제가 메소드 (Method), 전달 값 (Parameter), return 개념을 공부하는 도중, 갑작스레 개념이 헷갈려서 이렇게 글을 남깁니다. 나도코딩 자바편에 나온 동영상 강의와 함께, 커뮤니티에도 등록된 글을 보면서 다시 한 번 복습을 하고 있는데요...ㅎString getAddress(){ return "서울시 어딘가"; }이제 전달 값, 그러니까 Parameter가 없는 메소드인 경우, 그냥 위와 같이 return으로 문장을 출력하는 반면에, 갑작스레 parameter와 return이 함께 있는 메소드가 헷갈리더라구요...ㅎ(반환 타입) 메소드 이름 (전달값1, 전달값2, ...) { 반환 값 선언 // 예시 : int result = 0 // 메소드가 수행하는 여러 명령문들 수행 동작 1; // 괄호 안의 전달 값들을 사용 및 동작 수행 수행 동작 2; // 전달 값1, 2들을 이용하여 수행 2 수행 동작 3; // 전달 값1, 2들을 이용하여 수행 3 ... return 반환 값; // return result - 결과 값 반환 }int add (int x, int y) { int result = x + y; // 이미 int result = 0;을 내포함 return result; }제가 위의 메소드들에서 이해 한 부분은 (혹시 몰라서 다른 예시도 들고 왔습니다..ㅎ), void를 제외한 나머지 자료형 타입 (String, int 등...)들은 return을 가지고, 이 때 return을 하는 것은 반환 값이 되는데, 여기서 return 반환 값은 이미 이전에 괄호 안의 전달 값들을 이용하여, 수행 동작들을 마친 다음 반환 값을 저장하는 과정으로 이해하는 게 맞을까요? 이렇게 메소드가 수행 된 다음엔, main 메소드에서 참조변수를 통해 수행되는 과정으로 최종 결과를 출력하는 거구요...ㅎ 이렇게 이해하는게 올바르게 이해 한 것일까요?(반환 타입) variable = 메소드 이름(); System.out.println(variable);System.out.println();을 쓰는게 일반적이진 않지만, (다른 메소드를 불러서 처리하거나, 아니면 메소드 안에 이미 print문이 저장되어 있을 수도 있기 때문에) 제 스스로 이해를 돕기 위해서 일련의 과정을 위에 나온 것처럼 제 나름대로 정리해봤습니다. 또한 프로그래밍 공부를 계속하면서, 객체 지향 프로그래밍언어(OOP)의 기초 부분에서 가끔 헷갈릴 때가 있는데 (평상시에는 잘 씀에도 불구하고,) 그 때 마다 좋은 답글을 남겨주셔서 감사합니다. 덕분에 어려운 Java 프로그래밍 공부 잘 헤쳐 나가고 있습니다 :) 다시 한 번 감사합니다 :)

7강에서 @GetMapping("hello-api") @ResponseBody public Hello HelloApi(@RequestParam("name") String name){ Hello hello = new Hello(); hello.setName(name); return hello; } static class Hello{ private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } }코드 중 궁금한 사항이 있어 문의드립니다.static inner class를 쓰는 이유 알 수 있을까요??그냥 innerclass와 접근 범위가 다르다는 것밖에 이해가 어려워서 조금만 더 잘 알고 싶습니다.
